Our own boat has a 1978 Yanmar 2QM15 direct cooled. It spent most of
it's
life in salt water - Never been overhauled and still runs perfectly.

Hey, that's my exact motor. Maybe we should form a club!



Stephen,
This group is about as close as we will get - It's a good place to discuss
these things. Then there is also the forum at
http://www.marinedieseldirect.com/ .

I have not looked too closely at converting to fresh water cooling, but I
think someone once said I would need a different exhaust mainfold to do
this. Looking at cooling circuit, I am not so sure. I will start a new
thread about this.
